The 6S19P is similar to the American 7233, which is not cheap or common even here in America. The pinout is different. The 6S19P is common on Ebay. I got a box full from the Ukraine for $3 each. It is probably close enough to 1 section of a 6AS7 that a 6AS7 could be made to work.

thanks for all information
i think now, i will be able to find a similar tube
if i go for this headphone OTL ( Output Transformer Less ) amplifier

there will be a way.
if not find ABSOLUTE equal tubes for output,
will probably be possible to alter resistors in output

Is it two Tubes SRPP output?
.. unless I am mistaken

if looking at my schematic, in first post

Wouldn't it be possible to use 6H30pi in the output PUSH-PULL?

Of course, but You must make fase-invertor befor PP 6N30P /or selfinvertor - I have this one/.
